Conquest (Ravages of Honor)

The war for humanity's freedom is just beginning. 
Syteria is a survivor. She survived being kidnapped by the Matriarchy. She survived being turned into one of their slave soldiers. But even she didn't think she'd survive saving her brother's life, an act of treason. 
After the ship taking her to her execution crashes, she finds herself a stranger in a strange land.
Syteria's very existence threatens the donai--a race of genetically engineered warriors who overthrew the humans who created and enslaved them. Only one person stands between life and death, between freedom and slavery--Darien, a half-breed donai prince who defied his emperor to rescue her, a derelict spaceship's only survivor.
His motives are suspect, especially when turning her over to the tender mercies of the Imperium would cost him nothing and redeem him in the eyes of the emperor.

To save their societies Darien and Syteria must risk everything--even falling in love--to forge an alliance that will change everything.
